【 摘 要 】

The paper presents a study on the optimization of the bioscouring treatment of 60 % of cotton + 40 % of flax blended material by using a commercial enzymatic product called Beisol PRO, Denimcol Wash RGN (detergent) from Bezema Company, Switzerland and sodium citrate (complexing agent) from Sigma Aldrich.The bioscouring treatment is imposed by the specific natural structure of the fabrics. Both cotton and flax have different organic and mineral compounds which need to be removed during the specific pretreatments applied in textile industry. In this case was chosen an alternative of the classic alkaline treatment. The alternatives propose is an eco-friendly one due to the fact that the temperature use is lower comparative with the classical one (55 oC, respect to 90 oC) and the waste waters pH is in the neutral range.For treatment optimization, a mathematical model of the 2nd order was created by a central, rotatable second order compound program with two independent variables: enzyme concentration and treatment time. Based on the values obtained for the weight loss of the treated samples, the mathematical model obtained was analyzed from the technological and graphic point of view, and the optimum parameters for the bioscouring treatment with commercial product Beisol PRO have been set. The best results were obtained in case of 2.1% of enzymatic product and 39 min. of exposure.
